AUTOMOBILE-HORN. I

To all whom it may concern Be it knownthat I, HENRY; CHARLES Eva- LYN, a citizen of the United States, residing at Chicago, in thecounty of Cook and State of Illinois, have invented new and useful Im rovements Automobile-Horns,- of whlch the followingis a specification? The present invention :relates to horns or' whistles and more-particularly thoseio erated by the exhaust from. internal com ustion engines, and thelike, though .it will be clear to those skilled in the art that. it is not limited to this particular use. The primaryobject of the present invention is to; provide a simple, compact, and thoroughly practical structure that will either deliver-the exhaust :into the sound producing memberor members, or into the open air,1 at the same time, constitutinga protector for maintainin the parts substan-. tially free from dirt an dust, thus making it especially ap lioablefor use on automobiles and the: e.

Two embodiments. of the invention are illustrated in the accompanyingdrawings, but it is to be understood that said invention is not limited to the precise details of the two forms of construction disclosed.

. In the drawin Figure 1 is aside elevation of one :em imBDt' .of the invention. Fig. 2 is a longitudinal sectional view therethrough. Fig. 3 is a cross sectional view on the line 3-3 of Fig. 2. Fig. 4 is a view partially in elevation and. partially in section of ayniodifiedi form of construction. Fig. 5 is an end view of the valve member Fig. 6 is. aviewthat is nera'll to the exhaust 0 engine.

Referringfirst to Fig. 6, the frame of the automobile or :vehicle is designated generally by the reference numeral 7, andmounted in;the'front portion thereof, beneath a hood 8,'is "an Internal combustion engine 9 that may hoof any desired or welh known type. fromthis engine, is an:exhaust .pipe"10 t at :eondu'cts the ex- Specification of Letters Patent.

will be note ,has an open discharge end 15, extending through the lower portion ofsaid delivery ducing elements can 0 Patented Ap'r. 22', 1913;

livery member 14 that is also in: the form 1 of an elbow. The deliverymember consti-b tutes a part'of'the horn or whistle, and acts as a sup ort for the remainder of the mecha 2, and' the elbow 13 can of course be changed, in order. that the device can be mounted on mufllers having discharge pipes of various diameters.

Referrin first to. the embodiment disclosed in 1, 2 and 3 respectively, it

member, and projecting axially and hOl'l zontally through theldischarge end thereof,

is a sup rtingrod 16. This rod is slidably mounte' in a .boss 17 formed on the rear portion of the member 14. -It is'furthermore provided with a longitudinally disposed keywayor groove 18. A set screw 19, threaded haust to a mufller 11, and from one end of this mufiier pipe 12.

e0 1 .nism. t is secured; to the elbow 13 pref- I erably by a setscrew 15, illustrated in Fig.

hat the delivery member 14 i into: the boss, has its inner end engaged in the key-way, and firmly clamps the rod 16 in its adjusted position, while preventing 1 the taming of the same, even when [the set screw is-loosened.

Mounted [on the projecting, end of the supporting rod 16 and clustered about the same, are a plurality of 'soundroducing elements, in the form of hollow cy inders 20 of different. lengths.- These cylinders have open receiving ends 21spaoed apart and arranged in opposition to the open discharge 'end15 of the delivery member 14. Their opposite'ends are closed They are suitably securedqto therod16by'webs or other devices 21",,and their 0 en ends are suitabliy .formed to produce whistles, as will be rea ily understood. This u of soundro- 5301?. be adjusted toward and from thedelivery member 14 b loosenin the screw. 17, inasmuch as this will permit t e sliding movement of'the rod, as

above explained. i

Interposed between the delivery member 14 and the 'sound'producin members, is a controlling-element, in the orm of a valve I 22, which valve is provided, with a central:

openin that slidably receives the rod 16, so

'that'sald valve is movably mounted on the rod. It is furthermore provided with 2. lugor key 23 that is slidably engaged in the key-way or groove 18. The valve 22 isprovided with a shield 24 that slidably extends 'over the upper part of the delivery member. 14, and it also has a plurality of shields or? guard lips 25 that. slidably move alongside. the inner ends of the soundproducing mem-' bers 20. Referring now moreparticularly to Fig. 2, it'will be observed that the inner -wall-of the discharge end of the delivery member 14 is provided with a plurality of outwardly extending grooves 26, and the valve has ports 27 therethrough that term1- nate in grooves 28, which coact with the" grooves 26, to produce directing nozzles when the valve 22 isagainst the endof the delivery member 14. 'Inorder to produce a practically tightfjoint, when in this latter position, the delivery member terminates in-- an annular rib 29, and the opposingface of of the sound-producing members 20, and is normally held in this latter position by means of a coiled spring32 surrounding the rod 16,- and suitably secured thereto and also, secured to the valve. -When in this position, it will be evident. that the imlct ends of the sound producing cylinders will 'be substantially closed. Inorder to move the'valve to the position shown in Figs. 1 I and 2, suitable devices under the. control ofv the operator of the machine, are employed. Thus in Fig. 6, there} is illustrated a pedal,

33,having adependin arm 34, to which is connected alink 35. his link terminates in.

ayoke 36 that is pivoted,,'as illustrated-at 37., to the valve element. H

z-Brie'fly described, the operation of the structure is as follows: Under normal conditions, or 'when there is no pressure upon the pedal 33, thesp'ringi32 Wlll hold the valve over the open inlet ends of the sound producing'tubes 20, as illustrated in Fig. 6. .'1 heexhaustrfromthe engine can thereupon escape into the'open. air, and-Lin fact will be de- A flected .from the tubes 20. When .i t-isdegsired tol sound an alarm, the operator has (only to pr'essuppn the pedal 33,'whereupon the spring 32 W111 be moved to. the position shown i-n igs'. land 2. Whenin this posi- 20, and sounds will thus'be emitted. Upon .rwct to draw pos tion. I a v, .-It W111; beevident that this structure is releasing thepedalg33, the spring 32 will the valve member back toits exceedingly simple, and is entirely practical.

- It permits. the necessary adjustment of the parts to secure various tones and proper coaction. At the same time, inasmuch as the valve member is normally over the open ends 'of the tubes, dirt and dust will not, find 1 ready access intov the "latter.

Another embodiment of the invention is illustrated in Figs. 4 and 5, and in some respects, this form of structure .is considered preferable. The delivery member is illustrated at 38,and adjustably mounted thereon is the supporting rod 39 carrying the sound producing tubes or members 40. The valve orcontrolling element isshown at 41, and is provided with the shield42 and the guard lips 43. In this-instance, it will be noted that the said lips 43, instead of being made integral with the valve, are carried by a stem '44 threadedinto the valve; A guide screw 46 that extendsthroughthe parts, engages in the key-way 47, to prevent the relative rotation of the parts, andalso serves as a lock to hold the valve and stem-againstrelative movement. A spring 48, mounted on the rod is secured to the valve, and normally holds the same against the openends 0f the tubes 40. The yoke for movinggthe said valveagainst the action of the spring, is shown at 49. In this embodiment of the invention, it will also be noted that the said a I valve element carries a plurality of delivery nozzles 50 that serve to" direct the exhaust properly into the sound producing v tubes. It isbelieved that this embodiment ;of the invention will be entirely clear; from what has been described "above.

construction, operation-1; and manyadvan- :tages of the herein described invention will be apparent to those skilled in the art, without further description, andit will be understood that various changes in the size, .shape, proportion, and minor details of cone struction, may be resorted to without :de-

partingfrom the-s irit" or sacrificing any of the advantages oi the invention.
